The NELD-DTV concrete dynamic elastic modulus tester was developed by Beijing NELD Intelligent Technology combining advanced technology both domestic and across the border. It is dedicated to measuring the change in the relative dynamic elastic modulus before and after the freeze-thaw cycle tests. The product uses piezoelectric sensors and imported monitor, and provides high test accuracy and repeatability, simple operation and scientifically-designed structure. Pairing with freeze-thaw cycle testing equipment, this is the more scientific and ideal products. This tester is suitable for measuring the dynamic elastic modulus for a wide range of materials like concrete, carbons, slates, glass, bricks, plastic and metals.
